HPB Honeywell Precision Barometer HPB The Honeywell Precision Barometer (HPB) offers outstanding value to instrument builders requiring accurate and stable barometric measurements in real-world conditions. The HPB uses proven silicon sensor technology with microprocessor-based signal compensation, eliminating the need to insulate or temperature-regulate the barometer. The HPB has a pressure range of 500 to 1200 hPa. The HPA, intended for altimeter applications, provides a pressure range of 0 to 17.6 psia. APPLICATIONS: AWOS Weather Systems Remote Meteorological Stations Ocean Data Buoys Environmental Data Logging Secondary Air Data Altimeters Outstanding Value Small, Rugged Design ±0.4 hPa Accuracy From -40 to 85ºC FEATURES AND BENEFITS ISO-9001 ISO-14001 High Accuracy 0.4 hPa max from -40 to 85C 0.03% FS max from -40 to 85C Two-tiered accuracy including temperature errors over -40 to 85C Multiple Interface Options Interface, Plug-and-Play for your system requirements. Easy TTL – for lowest power consumption (33 milliwatts) – HPB, 0.4 hPa or 0.8 hPa; HPA, 0.03% or 0.06% FS Max. Simplifies System Design – there is no need to insulate, temperatureregulate or provide additional signal compensation. RS-232 – receives commands and sends data to a single serial port of a computer. RS-485 – up to 89 units can be connected to a two-wire multidrop bus. Proven Honeywell Technology and Reliable – Honeywell has been building the world’s highest Stable performance silicon pressure sensors for over thirty years.
